Design for Phablets

I spent last week at Mobile World Congress 2013 in Barcelona, where Synopsys also demonstrated our D-PHY, CSI-2 and DSI protocols running in hardware and connecting to Agilent test equipment and UNH conformance test suite.

The Need for Speed – D-PHY

I cover topics about low power and mobile applications in the past years but there is something that is often neglected. It comes at the expense of lowering the power and it is performance. We can argue that minimizing power consumption is dependent on what kind of power we’re reducing (for example static or leakage vs. dynamic power) and its effect of the performance but we know that there is no void in physics and Higher Voltage threshold for example reduces leakgae but affects max performance. The problem we have is that as much as we need lower leakage power and lower dynamic power to prolonge the battery life between charges, we also need high performance as we don’t want to wait for an application to load itself or transfer data to our mobile device. As part of my role I track the operating performance of Image sensors and Displays and one of the good measurements is the maximum bandwidth used by the camera interface CSI-2 and display interface DSI. I discussed this with David Wolfe (reference my interview with David here) and he provided me some statistics observed as part conducting interoeprability events in the past years.

Mobile solutions at Work

We typically refer to mobile solutions in the context of consumers as these mobile devices are used in our daily life for fun, accessing information, watching movies and similar tasks. We also use these Mobile electronics for work related tasks: phone calls, texting, email, business apps and for accessing / sending information.

#1 Camera Application

What application sells most image sensors in the world? As you probably figure out it is not Digital Still Camera or other consumer electronics used to capture photos or videos like a camcorder. Almost every mobile phone comes with a camera (image sensor), same with tablets. Sometimes 2 cameras are standard feature, capturing front and back. Based on latest information from iSuppli mobile handset account for ~ 1.66 billion Image sensor units shipped out of a total of 2.1 billion CMOS image sensors (79%). But there are both CMOS and CCD image sensors. You can find CMOS and CCD image sensors and these are two different technologies for capturing images digitally, both convert light into electric charge and process it into electronic signals.

Infectious Mobile Trends

We are surrounded by electronics that make ourselves accessible all the time. It can be at work, while driving, at night while watching a movie or having fun with family, or at a social event. The mobile device is used for socializing using several tools including instant messaging, social network, voice call or video call. With cameras used widely in mobile electronics and the availability of broadband wireless communication it’s easy to make video calls from the device. The thing with mobile is that it tends to ‘infect’ other electronics around it… we now have home electronics such as TVs, Gaming and Set-top-boxes that incorporate cameras, wireless connectivity and app’s which allow to make video calls. All of these originated from the PC/laptop and accelerated with mobile usage that got people hooked.
